FAQs
What installation steps are recommended when pairing the R9000 FF with existing bussed gutters? Start by verifying the underground feed is within 1200 A capacity and that the four-wire configuration matches the system design. Ensure surface mounting clearance, proper lug seating on the 6 studs/Ø line lugs, and alignment with the gutter network. Maintain UL/EUSERC compliance and use appropriate hardware for galvanized steel components to maximize longevity and reliability.
The R9000 FF supports 1200 A amperage, three-phase power, and an interrupt rating of 65 kAIC. It accommodates four conductors (load lug size 4 x 600 MCM) with six studs per lug arrangement (6 studs/Ø) and is designed for underground feeds, surface mounting, and ANSI 61 gray painted galvanized steel construction, ensuring robust fault protection and serviceability.
Yes. The R9000 FF carries UL certification and is EUSERC approved, which means it meets recognized safety and utility standards. This helps streamline utility coordination, project approvals, and compliance audits for industrial and commercial distribution systems that require proven, inspected enclosures.
The galvanized steel construction with ANSI 61 gray finish offers excellent corrosion resistance, reducing upkeep in harsh environments. Its rugged, surface-mounted design simplifies inspection and wire access, while UL and EUSERC certifications reduce rework risk during audits. Overall, the cabinet supports predictable lifecycle costs by minimizing corrosion-related downtime and maintenance interventions in underground distributions.
This cabinet is ideal as a termination point before bussed gutters in underground, three-phase power distributions for industrial facilities. Its 1200 A capacity, 65 kAIC fault rating, and 4-wire configuration make it suitable for large feeder terminations, utility-aligned installations, and environments demanding durable finishes and ease of installation with surface-mounted access.
